This is spike from Hurricane Fluttershy when the film caught on fire. This is also my first successful use of Ponyscape
. It is definitely buggy, but things like power strokes make it really nice. If you do vectors I would suggest at least giving it a try.

You can open it in non-ponyscape, but the wonder of power strokes is replaced with shapes with a ton of nodes. (Test in Inkscape 0.48.4)
I don't own MLP:FiM or Spike.
